What do you think?
I think there is no criterion for importance. The people whom we consider important do not consider themselves important. Only others perceive them to be important. If importance is a matter of perception, you have to first perceive yourself important.
As for me, to be an important person in the society, we don't really have to please anybody. By showing respect and concern to others, you show others that you are an important member of the society. You have to do the duties of a normal person in the society. Always obey the rule and set an wxample of being a nice person.
